Hmmm - the new carpet makes the seats look grubby. Actually the photo looks worse than they appear to the eye.
I found the carpet easier to fit than I expected. I used a Coverdale set which comes in two sections, front and rear. That way it's pretty easy to fit the rear first and find the holes for the seat belts, handbrake and the plates the seat rests on. Then front part goes in, which is bit trickier. I needed to trim the part around the heater (whilst doing that I found why the heater was pumping out heat even in mid-summer, the clip had fallen off the flap), also need to cut for the steering column.
I didn't remove the gear lever in the end. All I did was take an estimate where the lever was and cut a cross cut to allow the lever to protrude through the carpet to get the rough position. Then I removed the rubber gaiter and cut the carpet into the metal 'ring' around the base of the gear lever. It worked quite well.
It needs to settle a bit, and the cut of the carpet is a bit generous around the transmission tunnel, so it's a bit loose, but I reckon it will settle down after a while.
